One of the last events this year in Europe will be the LinuxDay 
Some more details about the event:
Date: 27. November 2010 (2010-11-27)
Time: 09.00 till 18.00
Location: HTL Dornbirn, A-6851 Dornbirn (near the Swiss, the German, and
the Austria border, right beside the Bodensee.)
Deadline CfP: 26. September 2010
It's a small one-day event with a nice social event in the evening. The
audience is mixed (from novice to pros) and often it's not very crowed
(perhaps 200 visitors).
There is a wiki page  available. Please take the ownership or add
yourself as a booth person.
Just to note: I took ownership of the event and would like everyone
who lives nearby (or likes to travel :) to join up.
